MCDONALD'S is urging customers to pre-order their food using its app to help speed up drive thru queues which have seen some wait up to TWO hours to get served.
Once customers reach the front of the queue they must first order their food and then pay before picking up their food - but a spokesperson for McDonald's told The Sun that they can skip the first two windows if they pre-oder via its app.
Customers can even order their food from home and the restaurant won't start processing the order until you are 100 meters away from the restaurant.
McDonald’s has warned it could be forced to close drive-thru locations today if queues get out of hand.
A spokesperson said: "One thing that is slowing the queue down a little at all the restaurants is people not knowing what’s on the limited menu.
"People are getting served much quicker when they’ve ordered via our app, as whilst they have to queue to get there, they order from home have seen the full menu, so then drive to the store and once there speed straight through the first two windows."
Some devoted fans have been "waiting up to two hours" to get their hands on big macs and nuggets.
One customer said on Twitter: "Can't believe the queue for McDonald's drive thru is 2 hours", another added: "I thought there had been a car crash because of the traffic in town, turns out it was just the queue for McDonald's after it open the drive thru again."
A third said: "Huge queue to get into the McDonald's drive thru in London. The queue was more than a mile."
